Bearing Basics

With a constant cross section, thin section bearings allow for significant space savings and overall system weight reduction — ideal advantages when designing sophisticated and critical-application products. The cross section, which is usually square, remains constant even in bearings with large bore diameters. Often used when space limitations or specific design configurations prevent the use of conventional bearings, thin section bearings allow for versatility in many applications and come in a range of contact angle designs, including radial contact, angular contact, and four-point contact.

Generally speaking, the majority of bearings, cam followers, and other rolling elements are manufactured from AISI 52100, a degassed low-alloy chrome steel blend with significant concentrations of chromium and carbon. AISI 52100 has high hardness ratings and excellent resistance to wear and deformation.

Temperature is extremely important when choosing a bearing. Whether due to friction, electrical current, electromagnetic induction, or an extreme external environment, bearings are often required to perform in high temperature environments.  We’ve provided this quick article to help you understand the essence of what it takes for your bearing to take the heat.

The purpose of a rolling bearing is simple, reduce the rolling friction while supporting the applied load. Most rolling bearings are composed by two concentric rings – known as the inner and outer race – separated by a set of evenly spaced elements rolling in between them.

Selecting a bearing requires choosing a series of parameters, including not only the most appropriate type and correct size, but also the right material. In fact, making sure that the material has the appropriate strength and toughness for the design is extremely important for a bearing. 

At Emerson Bearing we are fully dedicated to our customers, and take pride in making outstanding products as well as providing accurate documentation of their performance. Our bearings are engineered and manufactured with the highest levels of precision, and uphold the highest quality standards, however, no bearing lasts forever. So how can you be sure that your bearing will perform well throughout its life?
